So while I was driving around last night, I noticed a pulsed vibration coming from what I think is the front wheels. It varies with the speed of the car, more frequent at higher speeds, less frequent at lower speeds, in sync with each rotation of the tire. I checked the tires, no odd things there, checked air pressure and still pulsing at correct psi. Maybe something to do with the brakes? Pulse is stronger when turning right than left.

I have no clue where to start looking or what I'm looking for. Cupped tire? Stuck caliper? Any thoughts?

 

Improper rebalanced and rotation?

Or could be as simple as a stuck nail or a hex bolt between treads throwing ur balance off.... inspect the tires visually first

 

If it changes when you are turning, it could be a wheel bearing. My wheel bearing made a pulsating low frequency airplane like noise that got worse at speed, on an older civic it made a high pitched pulsating noise. You can rotate you tires and see if the noise moves with them. Also, keep an eye out for excessive brake dust on a rim, my moms Highlander had a stuck caliper and it had a pulse/vibration similar to what you describe and it resulted in a lot of brake dust accumulating really fast on that rim.

 

How many miles are on the tires and what bran are they? It could be an issue with the tire itself as the tread has worn down.

 

+1

I've noticed that some tires will cause some pulsing sounds when they start to get worn, which is annoying.

 

Thanks for the replies. I know my front tires are starting to get pretty worn, 37k on dunlop all seasons. Replaced the rears a few months ago. Only thing is it happened all of a sudden. No wheel weights missing, nothing stuck in the tires. Also, not sure if it is the fronts anymore cause I don't feel it in the steering wheel, more the floorboard and seat it seems. Anyways, looks like I need to invest in a floor jack to get the wheels off and do a thorough inspection.

Good news I guess is that if it is the tires, I was already thinking about getting 4 new pilot super sports soon. If its a stuck piston/caliper, I have the brake judder for the 3rd time and should just get new pads and rotors that don't suck like the oem ones do.

VMR, any chance you guys can get a 19x9.5 +45 rear for the V710? Like the look, but want staggered and a 19x9.5 +22 just ain't gonna fit on the sedan.

 

Some tires just get noisy after they've been worn down a bit. 37,000 miles is a pretty good amount for those all-seasons. If you're thinking of switching it up to some Michelin PSS, you will not be disappointed. Pretty much every aspect of that tire is amazing.

As for additional sizing, we will definitely be bringing in more sizing options in the future. Unfortunately for the next few production schedules though we do not have anything higher offset than 9.5 +22.

 

37k is really a lot for a Dunlop all-season. It definitely seems that its a pulsing sound from the tire being worn. Good news is that you can easily trouble shoot this by trying new tires.

 

Easily can check that, yes. However that could be an expensive venture! Haha.

If the tires still have a good amount of tread on them then he probably won't want to replace them.

 

I guess I was assuming at 37k that the tires were ready to go.

 

Would switch out tires

 

Just because they're noisy does not mean that they're completely done. It's just how tires get over time, from my experience.

 

So it was a nice sized hex bolt in the inside sidewall of the drivers front. Ordered new set of tires to replace the crappy overpriced dunlops. I only needed 2 new tires cause I had to replace 2 of them back in January, but it was only $100 more for a set of 4 potenza all seasons, much better reviews. Was going to get pilot super sports but I might be moving to the DC area and figured summer tires would be a waste.

 

I am glad you found it! Another reason which I noticed once or twice is simply air pressure is to low in one of your tires and the TPMS hasn't registered it yet. Hahah cheapest fix I have ever done (Thank you WAWA free air)

 

Well that takes care of one problem I guess haha. Michelin Pilot Super Sports are excellent tires so if you ever have the opportunity to run them in the future I don't think you'll be disappointed.
